Ice-associated communities colonize the brine-filled spaces and are exposed to major biogeochemical and physical changes: temperature fluctuations, salinity, dissolved oxygen, light, pH, the surrounding organic matrix, and nutrient stress. A key adaptive response is the formation of biofilms, which...
